[Android] Sdk method count

Nhan_Cao · 6 February 2016 12:09

Hi all,

I have problems when I integrate fabric into my project. UNEXPECTED TOP-LEVEL EXCEPTION (the dex 65K method limit). I try to set multidex but it’s not stable, some feature not found class rx occur. So I create new default app and include sdk for test method of sdk, it’s bit number: 57894 method. I think it’s problem for anyone want to extend it. Who can provide me a proguard file to reduce it. I has include file method count of sdk-2.22-legacy.

Hi Nhan Cao,

in EyeSeeTea we’re also integrating Crashlytics and the DHIS2 SDK in our projects, and we’ve experimented that problem, so here I tell you how we solved it.

Add to the dependencies of your project, in your gradle.build, the multidex library

compile 'com.android.support:multidex:1.0.1'

Create, if your project doesn’t have it now, an Application class that extend from Dhis2Application

public class EyeSeeTeaApplication extends Dhis2Application {
..
}
(after that, whenever you tell Crashlytics to integrate with your problem, it will probably introduce its code inside the "onCreate()" method)

4. Import MultiDex in your Application class (EyeSeeTeaApplication in the example)
import android.support.multidex.MultiDex;

5. Override in your Application class the attachBaseContext() method to make DBFlow work with MultiDex:
/**
 * Function used to make DBFlow compatible with multidex
 * @param base
 */
@Override
protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    MultiDex.install(this);
}

5. Consequently, in your AndroidManifest.xml there would be something like...
<application
    android:name=".EyeSeeTeaApplication"
    android:allowBackup="true"
    android:icon="@drawable/qualityapp_logo"
    android:label="@string/app_name"
    android:theme="@style/EyeSeeTheme"
    tools:replace="android:icon,android:theme" >
...

this is...you have to declare your application in your AndroidManifest.xml.

And I think that I didn't forget anything. I hope this can help you and anyone else with the same problems (enabling MultiDex in a project with DBFlow)


Best regards

Hi Ignacio Foche,

Thanks for reply. So in my previous mail, I had said

I had done similar like you (a lot results on google or stackoverflow). You can read full docs at http://developer.android.com/tools/building/multidex.html and noticed Multidex support for Android 5.0 and higher and Avoiding the 65K Limit part.

With this you’ll build success, but your apk higher, but if your project is injected some more lib using more annotation or not common declare (like reactiveX, dagger, retrolamda, … ) it will not work stable, sometime will crash with no reference error. That why I’m not continue with that solution and try to review and do anything about reduce method.

Yours sincerely,

Nhan Cao

Hello Nhan,

I am sorry for responding late. Some suggestions are below:

As a hacky solution, you can try to use default proguard configuration for debug builds. (android studio includes it by default when you create a new project).

If you have removed it, you need to modify your gradle build script by adding proguard configuration. You will also need to put proguard-rules.pro file in the root directory of your android project (if you have removed it):

        buildTypes { debug { minifyEnabled true proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } }

In this case, proguard will be used to strip out unused methods for debug builds.

In general, this approach is not recommended way of handling dexing issues, but in order to provide better solution I need more details about project dependencies or an access to your codebase.

Will be waiting for updates from you.

Best Regards,

Araz Abishov

Hi Araz Abishov,

Thank for your support. That way I usually do in my project when release or limit dex and avoid view/copy code. In first email I had mention

I just need content proguard some lib of dhis2-sdk. Anyway, I has removed some lib and refactor code and temporary success.

Noticed: in one app, can’t not use dagger2 and dbflow concurrent without proguard, should be separate module.

Thank you all.

Yours sincerely,

Nhan Cao
